View Full Version : Metabolic Setpoint

12-19-2001, 06:37 AM
don't know if this is the right forum for this...but let's talk about metabolic setpoints.

do you believe that genetically speaking your body has a specific weightrange (metabolic setpoint) that it would prefer to be at?

if so, do you think there is a way to reset higher or lower as the case may be?

do you think that setpoint is set in stone?

Not sure if it's set in stone. I'm pretty sure it moves with age, but it's there.

I agree with Yates. When I was in my twenties my weight wanted to stay around 145lb, I could loose weigh but to gain any was very hard. Now that I am in my thirties my weight wants to stay around 160. In that time period I had to get fat inorder to move up in weight. Right now I am trying to gain weight and finding it very difficult even though I am eatting about twice the amount I use to.

my weight just keeps pulling towards 200 lbs.

12-19-2001, 08:53 AM
I've been stuck at around 170-75 since i started training.

I began lifting at around 160 and the only times I've gone under 170 are when I have been sick.

Yea. My body wants to weigh about 150. 6.5" wrists and a 28" waist (when I'm in shape lol) just aren't designed to carry 200 lbs.

Your body naturally sets the weight higher as you age.

I don't think you can permanantly lower it.....you can by adding muscle and losing fat....but if you were to stop training....the effects would be lost...thus not a permenant fix

Over time our metabolism naturally slows down, correct?

12-19-2001, 09:37 AM
I think one of the reasons most peoples metabolism slows down as they get older is because they become sedentary.

also when we get older we are in a less anabolic state
less growth means we need less cals

Growth Hormone levels decline as we get older.So does the fat loss rate.However you can maximize growth hormone release by following a diet low in sugars and high glycemic carbs as well,by sleeping 7-8 hours every night and by staying active.But.. eventhough we can maximize its release,we can't make our bodies release more than they can.These levels indeed decline as we're aging and in addition the changes won't be as big as we wish to.

We all have a setpoint.We can increase our metabolisms by taking thermogenics,doing aerobic and anaerobic activities by adding muscle mass etc.
But the guy who eats wtf he wants and stays lean without working his ass out will always remind us that we all have a different setpoint.Or a limit to express it better.

Our bodies will always try to be around that limit.Sometimes they go on starvation mode and sometimes they try to store additional bodyfat.

We can't change it but we can always try to change our diets/exercise plans to somehow trick our bodies and achieve a better body shape.

There are persons that can tolerate carbs,eat a ton of carbs and stay lean all year round.On the other hand,there are persons that have a poor insulin sensitivity and have to keep their carb consumption fairly low.That's why blood tests are available.If you believe that carbs are the reason why you're not able to loose bodyfat,then do a blood glucose test.Then you can judge carbs and if they're guilty,you know:Kill 'em :D Eitherway,your diet simply sucks and you have to revise it asap.

Then,you might be consuming less calories than your body needs.In other words you may be in starving mode.If you're there,you'll have to gradually increase your calories by adding 100-300 every 10 days until you reach the limit.The scale will temporally stop going up or down when you reach the limit.

Finally,do a blood test to test your thyroid hormones levels.Low levels of T3 and T4 are signs that you do not have enough thyroid hormones.Also, an elevated TSH is a sign of thyroid deficiency.When your TSH is high,it means the pituitary gland is trying to make the thyroid gland produce more hormones.
You can also do something else:Upon awakening,with as little movement as possible,place a thermometer firmly in your armpit or under your tongue.Keep the thermometer there for 10 minutes.Record the readings on three consecutive days.A normal functioning thyroid should have a reading of 97,8 to 98,2.A reading of 97,8 or even lower,may indicate low thyroid function.You may need to supplement your diet with some minerals,like:vitA,vitB complex,vitB12,vitC,vitE,Coenzyme coQ10 and especially the minerals magnesium,manganese,selenium and zinc.

There are several ways to understand where your limit is setted and you have to try and try and try to get really close to it.It's really important to know where it's at because it's the main factor for determining how many calories you need in order to bulk or cut up.

so what about those people that lose like a 100lbs.....or conversely those that may gain a 100lbs?

have they managed to fool their setpoint? has it been changed higher or lower?

if they were to stop doing whateve rit was they did before, would they creep back up or down to wherever there body was before they made changes to their lifestyle? or have they created a new setpoint....perhaps midway between where they were and where they are?

The setpoint is primally depended on the body's hormonal balance.If you're able to manipulate it,you win the game.

People who loose weight fast or gain weight fast,always stall somewhere.I wrote before"The scale will temporally stop going up or down when you reach the limit."

The difficult is to build up a higher setpoint than your current one and the truth is that once you come back to your previous lifestyle,your setpoint goes back to its normal levels or even worse it may go down.(due to weak thyroid function and other factors as well)

It's well known that all the hormone levels decline as we age,so does the setpoint.

You start with a given setpoint which goes down as you're aging and you always try to make small changes to achieve a higher one.You won't become an ectomorph when you're an endomorph.

Just because someone was 100 lbs overweight doesn't mean their body wnated them that heavy.

Eating thousands of extra calories daily will keep you there no matter what kind of hormone levels you got running through your body.

12-19-2001, 12:29 PM
so your saying those people were way beyong their metabolic setpoint to begin with.

You also have to differentiate between exactly what is causing the person to be overweight.

100 lbs of fat tissue is an entirely different story than 100 lbs of muscle tissue.

12-19-2001, 05:15 PM
could you clarify for me, what your getting at please, dl?

12-19-2001, 05:42 PM
Metabolic rate is dependant on a lot of things, but it basically boils down to a combination of thryoid activity, a person's daily activity level, and amount of muscle tissue present.

Muscle is metabolically active tissue, and arguably the determinant of just how much weight the body "wants" to have.

Fat, on the other hand, doesn't consume calories. Fat is just there.

Before I started lifting, I was 125 lbs. Without lifting, I'd probably be 130, 135 at the most. However, now that I've put on more lean mass, it'd be hard for me to get back down that low. Even with two months of no training and very little in the way of food, I never dropped below 170 lbs. My body had adjusted to that weight.

I believe that the changes induced by exercise cause a more or less permanent change in any setpoint that might be present. While its true that there's a limit in both directions, its feasible to think that the addition of muscle/lean mass can greatly affect what the body considers "average" weight.

thanks bro..that's the info i was looking for.....:)

Metabolic rate is depended on many,many factors.

Power is right.As he said,"Even with two months of no training and very little in the way of food, I never dropped below 170 lbs. My body had adjusted to that weight."

The bad thing is that your setpoint won't easily (or better,it won't ever) work for you.In simple words your setpoint may keep you to a given bodyweight even if you consume less calories than your mainteinance level but it won't easily keep your bodyweight at the same level when you consume more calories than the main. levels.
(info based primally on the thyroid hormones function and on the hormone "leptin" function)

any more ideas/opinions/experiences?
